Not quite likely, but it's possible ofcourse.

IMO there's no better solution than rsync, besides somewhat more hardware 
/ not that I'm aware of no.

You could also build one fileserver able to serve nfs, store mail in 
maildir format and put 2 boxes online running mail/http daemons. Return 
one server get loadbalancer instead and put that online. That would be 
more my idea of having high-availability. Ofcourse you could also put a 
layer 3 switch in front of it instead of a loadballancer. Make sure the 
hardware of the fileserver is at least able to do raid 1 and has a 
dual powersupply. That will help the keep the thing up.

Hth,
